, 'i vi -To all whom it ma?) Concern.- i

Beit known that I, WILLrAn M. Pownn, s. citizen of the United States, residing in Port Chester, countyiof Westchester, State of New York, have invented a eenV tain new and useful Improvement in Ball-Bearings, of

which the following is s description. v

The object I have in view is the production of a ball bearing for crank shafts, to be applied to shafts in which the web and pin are permanently secured together, the particular object being to reduce the `aridth of the boerng, 'anddo away with enlargements on the pin. I nttain these objects by the mechanism villustrated in the Y accompanying girnwings, in which,

Figure 1 is s. side elevation of e. bearing embodying my invention. Fig. 2 is a sectional view thereoi taken on the lines 2--2 of Fig. l, the locking sleeves being' shown in elevation. Fig. 3 is a sectional yview taken on the line 3-3 of Fig. 2. Fig. 4 is a sectional view siinilar to that illustrated in'Fig. 3 but showing theY parte in different positions, as they are essembled. Fig. 5 is a diagrammatic view oi the inner bsll race, the pin and the lower locking' sleeve, in its rst position. Fig. 6 is a similar view showing the sleeve in its second position. Fig. 7 is a perspective view oi the lower loci;- ing sleeve; Fig. 8 is a perspective v'iew'of the upper locking sleeve; and Fig. Qmis a. sectional view similar to -Fig` 2 showing a modification.

In all the views like parts are designated by the saaie reference characters.

In carrying out my invention I provide e hell hearing similar to that employed in the Mercedes motor. This bearing comprises an outer continuous ball race l, an inner continuous race 2, and a. series of bells` 3. As shown in the drawings, eight balls are employed but the number may be varied in accordance with requirements. The balls are separated by cylindrical bodies Vform a foundation for the inner of felt 4, which contain lubricant, each cylinderoi felt being surrounded by a spiral spring 5. The spring structure is suflciently large to rest within the ball races and will not drop out at the sides, but is sufliciently Yflexible to be distorted and inserted from the side. The number of balls is so proportioned in relation to their diameter that when hunched together in one part of the ball race they occupy a 'space loss than half the circumference of the ball racc, sec Fig. 4, so that by removing the felt cylinders and placing tllo balls together in one side oi the racejhc concentric position of the two reces can be changed forming un oponA ing through which the halls 'can he removed thus domolishing the structure.

This form. of ball bearing is very simple, clic-ap to construct and gives great satisfaction. l propose to cmpley itin connection with s. crank shalt securing it to the pin between the two webs. Heretofoc the pin has been provided with an enlarged conter, in order to race, the uncnlargod than heretofore..

portionof the pin permitting the rece to be turned lrom the web to the pin. In order to locate ,the bearing`in"'the`.center, the unenlerged portion of the pin mustb'e upon both sides of the enlarged center.- This makes'long heffing, which is disedvantageous. By my invention the enlarged centerportion of the pin is done ew'yi'ilili, and the pip is mademuch shorter In the drawings, 6, E, represent the webs; connected together by the pin 7. The pin'is ,ol comparqtively large size, but not so large as the inner bell race, and is made as short as posslhle,'being but little longer than the width of the hearing. The pin is preferably` formed integral with Athe 'webs although this is'not essential. The ends of the pin and web are beveled :et 8, andtthe dismetvssr of the pin is less than the width el the web, so that the latter extends s short` distance on #eechjgide thereof forming shoulders or ledges 9, 9, '1^

Aformed, coin i de the horl'zontldiameter of the pin, so thati the pin will be above and the other heli below shmildersielthoug'his not necessary. BetweenI ball race 2 and the pin are two locking sleeves 11, each semi-cylindrieel in shape.A The inner sieevelllfis of a length equal to the separating space between. the two webs 6, 6, so that when in place it will be engaged at its ends', with the inner feces of the two webs and will not move longitudinlly. The outer sleeve 1l is somewhat longer then the inner sleeve, so that its extremities will rest upon the ledges 9, 9, and rotation be prevented. The. sleeves 19 and 1l are adapted to make a tight fit with the inner ball 'race 2. In order to prevent longitudinal movement of the outer sleeve, spring bands 12, 12, are employed, these bands resting in grooves 13, 13, in the two sleeves. It is to be noted that the grooves 13 in the lower sleeve l0 are nearer the edges than those in the upper sleeve, sothat the grooves on the two sleeves will be in aliuement.

ln order to attach the bearing, the two hall races l and 2 with thehalls in place, are slipped along one of the webs 6 and placed around the pin. The inner race is sufficiently large to permit this to be dune, and the action is facilitated by the incliner] or beveled portions 8, 8 ol the Webs and pin. lhc bearing is then raisedtn cause the inner eide of tlm inner rucc tu engage with the bottom of the pin, end the lower sleeve lilis thon inserted above the pin and withiuhe mec (son Fig. 'This sleeve is thon turned around until it is under th(x piu in the position shown in Fig. fi. ll is thon inserted nllovo tho pin und tho spring bands l2, l2?,A phrased in position.

What 1 claim is:- 1. The conihinnilon with the integral webs and crankpin. of a bearing having a single continuons inner ball race and n single continuous outer ball race, `vvith n single row of balls wlihih the race, the races being both grooved to sustain thrust in either direction in addition to the radial lo`sd, and semi-cylindrical cnslngs introduced between the pin und ball race for holding the ball race in place.

2'lllc combination, with the webs and crunk pin of n bcnrlng having a sing-lu continuous ball racey a single row of halls within the race, und semi-cylindrical cnsings hetween tile pin und bell race, the snid cnsings extending on bolli sides of the ball roce.

.i. The combination, with the integral webs and crank pin, of n bemim,V having a single continuous ball race, with a single row of balls therein, the races being both erooved to sustain thrust in either direction in addition 1o the radial load. a casing between the pin and race and separate means for holding the casing from endwise movement.

4. The combination with the webs` and crank pin, of a bearing having n continuons ball sce, a row of bulls therein, a casing between the pin i d race, the said casing being in the form of two sleeves, one of said sleeves extending beyond the rare on euch side.

The combination with the webs und crank pin, of a bearing having a continuons ball race, halls therein, and a casing between the pin and race, the said casing being in the form of two sleeves, one of said sleeves engaging with a web to prevent rotation.

9. In a ball bearing the combination with webs and an integral crank pin, the crank pin being of smaller-diameter than the width of the webs, so that shoulders are formed thereon, ot a bearing having a continuous annular race', balls within the race, and a support therefor intermediste the pin and the race,.the said support comprising two semicyllndrical sleeves, one of said sleeves resting upon the shoulders, and means for preventing endwise movement o! such sleeve, such mea'ns comprising bands surrounding the pin and sleeves.
